Topic: How to upgrade very old (not updated from long time) systems?

Hi there,

If the currently running version is too old - it's 0.9.8, what would be your advice:

1. To follow-up version after version upgrade;
OR
2. Just install latest version of the iRedMail?

The question is what should be more effective - the upgrade between any two given versions is a painful process, but should be preferable if in case of taking the second approach I will lose emails or any data?

Many thanks in advance.

Kind regards,
Cgavdar

CentOS 7 is still supported by iRedMail, and upgrading iRedMail from 0.9.8 to the latest 1.3.2 is not that hard, i suggest upgrading in-place. smile
